treewide: Use fallthrough pseudo-keyword

2020-08-23T22:36:59+00:00

Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

Remove superfluous breaks, as there is a "return" before them. Link: https://lore.kernel.org/r/1594724371-11677-1-git-send-email-wang.yi59@zte.com.cn Signed-off-by: Liao Pingfang Signed-off-by: Yi Wang Signed-off-by: Martin K. Petersen

scsi: ppa: use sg helper to iterate over scatterlist

2019-06-20T19:21:33+00:00

Unlike the legacy I/O path, scsi-mq preallocates a large array to hold the scatterlist for each request. This static allocation can consume substantial amounts of memory on modern controllers which support a large number of concurrently outstanding requests. To facilitate a switch to a smaller static allocation combined with a dynamic allocation for requests that need it, we need to make sure all SCSI drivers handle chained scatterlists correctly. Convert remaining drivers that directly dereference the scatterlist array to using the iterator functions.

scsi: flip the default on use_clustering

2018-12-19T04:13:12+00:00

Most SCSI drivers want to enable "clustering", that is merging of segments so that they might span more than a single page. Remove the ENABLE_CLUSTERING define, and require drivers to explicitly set DISABLE_CLUSTERING to disable this feature. Signed-off-by: Christoph Hellwig Signed-off-by: Martin K. Petersen
